94,937, and relates more particularly to the construction of the parts connecting the said standard and rotating table, to which the said standard is releasably secured. As heretofore designed the shock-forming standard when being withdrawn from the engaging parts of the rotating table'often develops a tendency to bind, and in consequence often bendsor breaks some of the operating parts. The overcoming of these ditiiculties is the purpose of my invention.

In the drawings, Figure 1 is a perspective" of the lower end of a shock-forming standard embodying my improvement, a portion of the rotating table on which the standard is mounted being also shown. Fig. 2 is a plan of the core-foot hinge-block, the peculiar construction of which constitutes the essence of this invention. Fig. 3 is an elevation of same. Figs. 4: and 5 are detail views of the flangeplate and flange-plate sleeve, respectively,-

which support the hinge-block. Fig. 6 is a section of the supporting-pin, showing a portion of the rollers journaled therein; and Fig. 7 illustrates a variation in the construction of the flange-plate sleeve and core-foot hingeblock, the variation consisting in the antifrictiOn-rollers being rotated on the member secured to the rotating table instead of upon the said hinge-block.

Referring to the drawings, A represents a portion of the rotary table of a corn-shocking machine, and B the main portion of the standard suitably sustained thereon. This shockforming standard B is preferably made of square gas-pipe and is held in position and driven by a suitable driving, member, here- 'erably four in number.

inafter to be more fully explained, which driving member is secured to the said rotating table A. A pin 0, projecting upwardly from the center of said table and through the driving member referred to, guides and sustains theshock forming standard when it is connected with the said pin and driving member.

0 isthe core-foot hinge-block,provided with lugs c, to which are pivotally secured the corefoot levers D. Journaling on stud-bearings c, which are oppositely located on the hingeblock 0, are the antifriction-rollers c pref- The hinge-block O is secured to the post B by means of the setscrew 0 and is adjustably connected with the core-arm hinge-block C by the rods M, which are threaded and screwed into the lugs m, all of which are shown in the general arrangement set forth in my application of August 9, 1902, Serial No. 118,986.

E and E are the upper and lower sleeves, slidably arranged upon the standard B. From the lower sleeve E extend the links I to suitable lugs on thefoot-levers D. Similar links Zconnect the sleeve E with the armsFon-the core-arm hinge-block C. These two sleeves E and E are adjustably connected by the rod E Further details of these parts,including the tripping mechanism connected therewith, need not be given, as they are not pertinent to this invention except to show the relation of the various parts. A detailed description will be found in the application above referred to. i

In Fig. 6 is shown a detail of the'guidingpin 0, which fits within the chamber of the core-foot hinge-block O. This guiding-pin is preferably madein two parts, as shown, the lower part thereof being preferably round, 0

- while the upper part in order to more readily engage the said hinge-block is made of smaller diameter and has journaled therein the antifriction-rollers 0 and 0, mounted on the'bearings 0 and 0 respectively. This guiding- 5 pin 0 on machines heretofore constructed had also served as a driving means'for the shockforming standard B, withits radial arms; but,

as previouslystated, when soarranged the standard was often withdrawn from the pm me with difficulty. To overcome this feature, however, a driving member of the following construction is used: The flange G is riveted to the platform A, as shown in Fig. 3. This flange is provided with an upwardly-extending cylindrical hub g, in the bore of which fits the pin 0, the fit being somewhat loose. On either side of the hub g are longitudinallyeXteuding oppositely-disposed ribs g. The sleeve H is provided with recesses 77,, corresponding with the ribs g, and is received and driven by the hub g of the flange G. A setscrew h secures the sleeve H to the hub of the said flange. Extending upwardly from the sleeve H are the arms h oppositely disposed and presenting an uninterrupted vertical surface to the rollers 0 when the flange G, sleeve H, and hinge-block O, supporting the said rollers 0 are in operative relation with each other, as shown in Fig. 3. These arms 72/2 impinge the rollers 0 and motion is imparted from the rotating table A through the flange G, the sleeve H, and the said arms 7&2 to the rollers c on the hinge-block O, and thus to the shock-forming standard B.

\Vhen it is desired to raise the completed shock from the table, the rollers 0 and 0 will prevent undue friction of the pin 0 with the bore of the hub g, and the two rollers 0 bearing against the arm 7L2, will operate to reduce friction at these points. The eifect of these rollers, it is thus seen, will be to permit the shock-forming standard to be readily Withdrawn from its driving connection on the platform and prevent any binding of these parts.

Instead of journaliug the rollers (3 upon the core-foot hinge-block, as shown, it is evident that they could as well be journaled upon the sleeve H and the corresponding engaging arms thereof transferred to the hinge-block, as shown in Fig. 7. It is immaterial which form is adopted, as either would produce the same result.

While only two of the rollers c engage the driving-arms 71 at any time, I prefer to have four, disposed as shown, for the reason that in rengaging these parts after a shock has been removed there will be less than onefourth of a revolution of the table until the said arms 72 will impinge the rollers c --that is to say, that motion will be imparted to the shocloforming standard very quickly after it engages with the driving memberwhereas,

were there only two rollers used the table might make almost one-half a revolution before imparting movement to the shock-forming standard.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a corn shocking machine a rotary shock-forming table and a detachable shockforming standard mounted thereon and driven thereby, in combination with a driving member for the standard secured to said rotating table, and antifriction-rollers secured to the foot of said shock-forming standard and adapted to be impinged by said drivingmember, substantially as described.

2. In a corn-shocking machine, the combination of a rotary table, a shock-forming standard and means whereby the said shockforming standard is detachably secured to and driven by the said rotary table, the said means comprising a driving member secured to said table, a core-foot hinge-block secured to the base of said shock-forming standard and engaged by said driving member, and antifriction-rollers journaled on the said hinge-block and adapted to be impinged by the said driving member, substantially as described.

3. In combination with a detachable shockforming standard, a guiding-pin, a rotating table, a driving member for the standard secured to said rotating table, and antifrictionrollers interposed between the foot of said shock -.forming standard and said driving member, the said antifriction-rollers being journaled upon the foot of said shock-forming standard, substantially as described.

4. In combination with a detachable shockforming standard,a guiding-pin provided with antifriction-rollers, a rotating table, a driving-sleeve secured to said rotating table, arms projecting upwardly from said sleeve, and antifriction-rollers secured to the foot of said shock-forming standard, said antifrictionrollers adapted to be engaged and moved by said upwardly-projectin g arms, substantially as described.
